Jennifer Lopez refused to have IVF (In Vitro Fertilisation) when she was trying for a baby.

The singer-and-actress was desperate to have children with husband Marc Anthony and although the couple were trying to get pregnant for a long time, Jennifer didn't want to seek medical help.

The 40-year-old beauty – who eventually gave birth to twins Max and Emme in February 2008 – told America's Elle magazine: 'When it comes to family and relationships, I'm quite traditional. Just because of the way I was raised. And I also believe in God and I have a lot of faith in that, so I just felt like you don't mess with things like that. And I guess deep down I really felt like either this is not going to happen for me or it is. You know what I mean? And if it is, it will. And if it's not, it's not going to.'

Jennifer – who married Marc in 2004 – recently revealed how she has to work hard at her marriage.

The 'Love Don't Cost A Thing' singer – who has been married twice before – said: 'What people don't talk about, which is interesting to me, is how you have to put as much work into your relationships as you do into anything else. We put so much into our careers, but there's also a lot of work that goes into making a successful partnership and marriage. It's not easy."
